DETAILED DESCRIPTION

This application claims priority to U.S. Provisional Application No.62/127,761 filed Mar. 3, 2015, which is incorporated herein by referencein its entirety.

Multiple variations are discussed of a wearable device 518 as shown inFIG. 1. Generally the wearable device 518 is made up of a display device202, and a securing device, 265 to which the display device 202 may beattached. In some of the embodiments, the securing device 265 of thewearable device 518 includes circuitry that can be in communication withthe display device 202, and can further expand the functionality andcapability of the display device 202. While examples are given of awearable device 518 that is a smartwatch, the wearable devices disclosedherein are useful in other formats.

With this in mind, the following description begins with a wearabledevice 518 with reference to FIGS. 2(a)-(d), which implements electroniccircuitry into securing device where the securing device takes the formof a band. The circuitry in the securing device may be configured toperform various tasks, which will be discussed in greater detail herein.The description continues with FIG. 3, which is a cross-sectional viewof an assembled wearable device 518, like that illustrated in FIGS.2(a)-(d). Next, the description continues with the flow chartsillustrated in FIGS. 4(a)-(b), which illustrate and describe twoexemplary, but non-exclusive, methods of assembling and/or manufacturinga securing device, for instance, like that shown in FIGS. 2(a)-(d) and3. Next follows the description relating to FIGS. 6(a)-(c), 7(a)-(c) and8(a)-(c), which illustrates various embodiments of, and uses for, thewearable devices 518, like the examples disclosed in FIGS. 2(a)-(d), 3and 5. Next follows the description related to FIG. 9, which illustratesthe steps of at least one embodiment where certain events areautomatically triggered by the connecting of components of the wearabledevice 518 from FIGS. 2(a)-(d), 3 and 5.

Turning now to FIGS. 2(a)-(d), a securing device specifically shown as aband is shown, which may be comprised of electronic circuitry configuredto communicate with a display device, 202. The securing device isillustrated in three different layers, 212, 224, and 232, which may beformed together into a securing device, as later shown in FIG. 3 at 265.Turning to FIG. 2(a), a display device 202 shown by example in the formof a watch that may be a smartwatch device is illustrated. The displaydevice 202 may contain any number of electronic components, includingbut not limited to a processor, memory, wireless interface (e.g.,BlueTooth), charging interface (all not shown), buttons, 206, and adisplay, 204. The display device 202 may also be capable ofcommunicating with an external device, such as a smartphone or tablet.In this way, the display device 202 may receive notifications from theexternal device to alert the user of the devices of an incomingcommunication or alert. In this embodiment, the display device 202 has aliquid crystal display (“LCD”) 204 configured to display contentsgenerated by the device 202. Those having ordinary skill in the artwould recognize that while a LCD is illustrated in this embodiment, anyother type of displays may be suitable for use with this invention, suchas e-paper, electronic ink (“E Ink”), organic light-emitting diodedisplays (“OLED”), or active-matrix organic light-emitting diode(“AMOLED”). The display device 202 as shown contains four tabs 208,which are designed to allow the display device 202 to be attached to thesecuring device, 265 in FIG. 3, which will be discussed in greaterdetail herein. The display device 202 may include a plurality of buttons206, which may enable a user to control the settings or functionality ofthe display device 202. While the buttons 206 disclosed are physicalobtrusive buttons, touch sensors could be used in lieu thereof, therebyconserving space on the side of the display device 202. Alternatively,the buttons 206 could be built into the display, which could be touchbased to allow a user to control the display device 202 without the needfor potentially obtrusive buttons placed on other portions of thedisplay device 202. The bottom surface (not shown) of the display device202 may also include an interface (e.g., pogo pins) for coupling thedisplay device 202 to the securing device, which will be discussed ingreater detail herein.

Turning now to FIG. 2(b), perspective view of a first layer 212 of thesecuring device is shown. A first layer 212 of the band is the outermost layer of the fully assembled apparatus. The first layer 212 may bemade of any material suitable to allow the securing device to be worn,such as leather, cloth, rubber, plastic, or other material. The materialuse can also assist in presenting a desired aesthetic. As would beunderstood by those having ordinary skill in the art, the type ofmaterial suitable for use as the first layer 212 may change depending onthe intended use of the band. The first layer 212 may be made of plasticbecause of its water-resistant qualities, rendering it capable of beingused in a water environment. A housing 210 is disposed between twosections of the securing device. The housing 210 may be comprised ofplastic, (e.g., Polycarbonate or Polycarbonate/Acrylonitrile ButadieneStyrene), metal (e.g., steel, or aluminum) or any other material. Thehousing 210 is designed to receive the display device 202 such that itis firmly secured or coupled to the securing device. This may beaccomplished by snapping the four tabs 208 of the display device 202into the four receiving members 214 of the housing 210 of the securingdevice. The first layer 212 may include a clasp connector 218. The claspconnector 218 is designed to attach to a clamp, such as clamp 219illustrated in FIG. 2(b). However, it would be apparent to those havingordinary skill in the art that the securing device could be closedaround a user's wrist using other connections, such as a ratchet,magnet, bucket connector, fold over clasp, toggle clasp, tongue clasp,or other fastener. Depending on the type of clasp used, clasp connector218 may not be necessitated.

Turning now to FIG. 2(c), a perspective view of a second layer 224(e.g., Low Pressure Molded (“LPM”) layer) of the securing device isshown. The second layer 224 also comprises a surface 226 interposedbetween two sections of the second layer 224, the surface 226 matingwith the upward facing surface of the housing 210 when the first andsecond layers are joined together. The surface 226 is designed to allowcircuitry within the securing device to interface with circuitry (e.g.,the display, processor, memory, etc.) of the display device 202. Aseries of through holes 228 may be used to allow pins on the bottomsurface of the display device 202 to electrically connect with circuitryin the securing device, which will be discussed in more detail withregard to FIG. 2(d). A rubber gasket 220 is disposed on the top of thesurface 226 around the holes 228, while a steel member 222 is disposedon the bottom of the surface 226 around holes (shown as 228 in FIG. 2C),providing some sealing for the interface between the securing device anddisplay device 202 and the securing device and other external circuitry,such as a battery charger (not shown). As will be discussed in greaterdetail with regard to FIG. 2(d), disposed within the second layer 224 isa third layer 232, which may be comprised of electronic circuitry, thethird layer 232 being secured to the second layer 224 by an adhesive orother fastener, such as a mechanical fastener like a spring biased pinor cotter pin. In one embodiment, the second layer 224 is formed aroundthe third layer 232, which in some instances may mean that the thirdlayer 232 is protected from exposure to liquid.

Turning now to FIG. 2(d), the third layer 232 of the securing device isillustrated in the perspective view. The third layer 232 is comprised ofelectronic circuitry which may be comprised of a Polyether ether keton(PEEK), transparent conductive polyester film, Copper indium galliumselenide (CIGS), or other flexible circuit materials (FCM) known in theart. As would be understood by those having ordinary skill in the art,FCM are typically comprised of: (1) a base material (e.g., polyester(PET), polyimide (PI), Polyethermide (PEI), etc.); (2) a bondingadhesive, which constitute a flexible polymer film that provides thefoundation for a laminate; and (3) a metal foil which is commonly usedas the conductive element. FCM are particularly advantageous becausethey allow for the creation of thin, flexible, and light circuitry foruse in unique applications, such as the band of a smartwatch, or similarelectronics. While FCM is described, it would be understood by thosehaving ordinary skill in the art that any type of circuitry capable ofbeing incorporated into the securing device may be utilized, such asprinted circuit board (“PCB”). The third layer 232 may be encapsulatedby the second layer 224 such that the third layer 232 is protected fromexposure to liquids. The third layer 232 is comprised of a firstcircuitry section 238, second circuitry section 240, and bridge layer242 connecting the first circuitry section 238 and second circuitrysection 240. The third layer 232 may also include a battery 234 capableof electronically connecting to display device 202 to act as theexclusive source of power or as an additional source of power.Alternatively, the battery 234 may act as a backup in case a battery ofthe display device 202 loses its charge. The battery 234 may be aPrologium Flexible Battery, ultrathin zinc-polymer battery, flexiblelithium ion battery, Flexible Lithium-Ceramic Battery (FLCB) or otherbattery material. In some instances it is beneficial for the battery 234to have sufficient flexibility to allow the securing device to freelybend without damaging the battery 234.

The third layer 232 may communicate with the display device 202 and/orother electronic circuitry, such as battery charger 244, via anysuitable interface. The charger 244 comprises a connector 246 sufficientto allow the charger 244 to maintain electric connectivity to the thirdlayer 232 and/or the display device 202 via a flat mating surface. Themating surface 231 may be a flat copper surface or plurality of surfaces(i.e., an upward facing and downward facing surface) on or embeddedwithin both sides of third layer 232, wherein the copper surface(s) arecapable of receiving: (1) electronic interface pins protruding downwardfrom the bottom of external device 202 and/or (2) electronic interfacepins protruding upward from the charger 244 or other electronic devices.In this manner, the display device 202 and charger 244 (or otherelectronic circuitry) may be connected to the securing device alone orin combination. The connector 246 may also include magnets to aid it ininterfacing with the downward facing portion of the mating surface 231.In this way, a user will not be required to physically snap or latch theconnector 246 to the securing device, which may be tedious and difficultgiven that the downward facing portion (not shown) of the mating surface231 for the charger connection may be on the bottom of the housing 210.The display device 202 may have pins 230 protruding downward from itsbottom for interfacing with the upward facing portion of the flat matingsurface 231 of the third layer 232 via through-holes 228. Specifically,a user may insert the display device 202 into the housing 210 bysnapping the display device 202 in place via the protruding members 208and receiving member 214, so that the pins 230 (in particular the pinscan be pogo pins) protruding from display device 202 engage with theupward facing portion of the mating surface 231 of the third layer 232.Likewise, the upward facing pins of the battery charger 246 may then beconnected to the downward facing portion (not shown) of the flat matingsurface 231 on the third layer 232. While in this embodiment pins 230and a flat mating surface 231 on third layer 232 are utilized tofacilitate communication between the display device 202 and securingdevice, it would be understood by those having ordinary skill in the artthat any type of connector known in the art for coupling electronics maybe used.

The third layer 232 may also include one or more miscellaneous circuits236 configured to perform a variety of functions. The miscellaneouscircuitry 236 may be configured to: (1) GPS track; (2) monitor health(e.g., skin resistance, heart rate/pulse sensor, and skin temperature);(3) receive/transmit wireless signals (e.g., for Wi-Fi, BlueTooth, NearField Communication (“NFC”), Radio Frequency Identification (“RFID”));(4) emit audible, vibratory, light shock, or visual signals; (5) act asan additional display (e.g., a small LCD display or a plurality of LEDsforming a display); (6) provide additional memory; (7) record/outputaudio or process audio commands to control the securing device ordisplay device 202; (8) charge a BlueTooth headset; (9) automaticallytighten the securing device to the precise size of the user's wristusing a material such as PolyPower DEAP material, which expands andcontracts with electricity; (10) allow a user to create their owncircuitry on the exterior of the securing device using, for example, abreadboard; (11) allow a user to control the securing device or displaydevice 202 using a touch sensor on the securing device; (12) allow auser to charge or communicate with the securing device and/or displaydevice 202 via an end of the securing device that comprises an interface(e.g., a USB interface); (13) automatically configure or control thedisplay device 202 and/or allow the display device 202 to automaticallyconfigure or control the circuitry layer 232; and (14) fingerprint IDusing the securing device.

Turning now to FIG. 3, a cross-sectional view of the full assembly ofthe assembled wearable device 518 from FIGS. 2(a)-(d) is illustrated.Full cross-sectional view 300 is illustrated with detailed view 302focused on the central portion of the securing device 265 and displaydevice 202. As shown, the first layer 212 is the outer most visiblelayer of the securing device 265, while the third layer 232 isinterposed within second layer 224. The display device 202 is securedwithin housing 210 via receiving members 214 (not shown). Chargingconnector 244 is coupled to the third layer 232 and display device 202via pins (not shown). A foam gasket may be used to seal around the pins.

Turning now to FIGS. 4(a)-4(b), flowcharts illustrating exemplarymethods of assembling the apparatus from FIGS. 2(a)-(d) and 3 are shown.It should be noted initially that the methods 400 and 425 are simplifiedflowcharts to represent useful processes but they do not limit thesequence in which the functions take place or even the functions thatmay take place in order to achieve the apparatus from FIGS. 2(a)-(d) and3. Indeed, those having ordinary skill in the art would understand thatthe apparatus can be formed using any molding technique, such ascompression molding, transfer molding, injection molding, insertmolding, and/or double shot injection molding.

As shown, the manufacturing process 400 starts at step 405 which mayinclude the forming of the second layer 224, by injection molding, whichwould generally be performed using a polymer, but may alternativelyinclude a metal (e.g., steel). Injection molding may be less flexiblethan utilizing spring steel as the base structure. Next, at 410 anadhesive layer is applied to a portion of the second layer 224. Theadhesive layer may be comprised of any material suitable to secure thethird layer 232 to the adhesive layer. At step 415, the third layer 232is secured to the second layer 224 using the adhesive layer from step410, for example double-sided tape. Finally, at step 420 the assembly ofthe circuitry layer 232, adhesive layer, and portion of second layer 224are overmolded, to create a further portion of the second layer 224. Thesecond layer 224 therefore encapsulates the third layer 232, containingthe circuitry. The first layer 212 may then be applied to the assembly424, which may comprise steel, leather, or another material (i.e., afabric layer). If it is desired to use a chain-link type material (orany material that has openings) as the first layer 212, it may behelpful to first overmold the adhesive layer and the third layer 232before applying the chain-link material (i.e., a fabric layer). This mayensure that the circuitry layer 232 is protected from liquid exposure.

While not expressly illustrated in the manufacturing process 400, a holemay be left in the top center of a portion of the overmolded secondlayer 224 of the securing device. Thermoplastic polyurethane (TPU) maythen be injection molded or a hard material may be low pressure moldedover the exposed center portion to form a water-resistant seal where thehousing 210 is secured to the securing device 265. The housing 210 maythen be secured to the center portion of the securing device 265 usingany number of ways known in the art, which were previously discussed.Alternatively, also as previously discussed, the housing 210 may befully integrated into the band by overmolding the housing 210 into thesecuring device 265. Additionally, a clasp, such as clasp 219, may beattached to one end of the securing device. The fastener may be designedto allow one end of the securing device to clamp to the opposing end ofit without the need for holes in the band.

In yet another embodiment of a manufacturing process, the manufacturingprocess 425 starts at 430 possibly with the forming of a spring steelframe, which would be part of the second layer 224, into a desired shapefor the band. Spring steel is very flexible but will typically return toits original form. Therefore, the spring steel frame must generally beinitially formed into the desired shape prior to implementing it intothe securing device 265. Additionally, because spring steel attempts torevert to its original form, it may be necessary to form the springsteel frame for an intended wearer's wrist size (e.g. “large wristsize,” “medium wrist size”). Next, at step 435 an adhesive layer isapplied to the spring steel frame. At step 440, the third layer 232 withany circuitry is secured to the spring steel frame using the adhesivelayer. The second layer 224 therefore encapsulates the spring steelstructure, adhesive layer, and third layer 232. Finally, at step 445 theassembly of the third layer 232, adhesive layer, and spring steel frameare covered with the first layer 212. Alternatively, the second layer224, adhesive layer, and third layer 232 may be overmolded and thencovered with the first layer 212. As previously discussed, the firstlayer 212 may also be comprised of a harder material, such as stainlesssteel. Such materials may be desirable by some wearers because of themore expensive appearance of the material.

The second layer 224 can be made with polymer or other material (e.g., ametal) suitable to achieve the objectives of a securing device withcircuitry third layer 232 containing circuitry. Moreover, whileadhesives are described, those of skill in the art would recognize thatany method of securing the circuitry to another structure may be used.Further, while certain embodiments may be described as beingwater-resistant, it would be understood that it is not required.

Rather than using a unitary securing device, the securing device may becomprised of numerous sections or modules, as shown in FIG. 5(a). Morespecifically, the securing device may be comprised of a plurality ofmodules 502 and 504, each module containing a portion of the third layer232 previously discussed. Each of these modules may be assembled inaccordance with the manufacturing processes previously discussed,whereby the third layer 232 (e.g., containing circuitry) is within thesecond layer 224 (e.g., overmolded layer), and then a first layer 212 isapplied. A module based securing device may be desired over a unitarysecuring device because each module may contain certain miscellaneouscircuitry of the third layer for handling different functions. Forexample, one module may contain circuitry for GPS, while another modulecontains circuitry for monitoring certain health parameters of thewearer. Such a configuration may be useful when a wearer is planning onjogging. Conversely, when the wearer is planning on attending a socialevent, the wearer may elect to replace the health monitoring module witha module configured to emit audible, visual, or vibratory signals.Moreover, the display device and securing device may be configured tocommunicate to one another and reconfigure each other based on thespecific module connected as part of the securing device. For example,when the GPS module is connected as part of the securing device, thedisplay device may download a GPS related application or automaticallystart such application if the application is already on the displaydevice.

Turning to FIG. 5(a) in more detail, a securing device 522 is comprisedof modules 502, 504 in disconnected form. The modules 502, 504 areconnected to the main body 506 of the securing device 522, which isconfigured to receive a display device (not shown) via display devicehousing 508. The modules 504 comprise the open ends of the securingdevice and include a connector 520 that connects one open end of thesecuring device to the other open end. While a generic clasp 520 isillustrated as the connector the securing device around the wearer'swrist, it would be understood that any of the previously discussed anddescribed connectors could be used instead. Each of modules 502 and/or504 may contain a portion of the third layer 232 which may includemiscellaneous circuitry configured to handle a particular function or aplurality of functions.

Turning now to the zoomed in perspective view of a module 502, themodule 502 has an overmolded body 510, a thinner flexible printedcircuit portion 512 that has been overmolded, a receiving portion 514,and a clip 516. The receiving portion 514 receives the flexible printedcircuit portion of another module so that electrical conductivity may beestablished across the connected modules. The clip 516 allows thereceived flexible printed circuit to be secured within the receivingportion 514. While not shown here, a first layer 212 may also be appliedto each portion of the modules, or a single first layer piece may beadded to cover the entire assembled securing device. When fullyassembled, the securing device and display device form a single wearabledevice 518, as illustrated in FIG. 5(b). As previously stated, however,each module may be replaced by another module containing circuitry thatperforms a function different than that of the module that was replaced.

Turning now to a more detailed discussion of the potential functionalityof the third layer 232, miscellaneous circuitry 236 may comprise GPScircuitry that may allow a user to see their precise location on thedisplay device 202 or track particular fitness related parameters,including, but not limited to, distance traveled and duration of thetravel. As shown in FIG. 6(a), the GPS tracking circuitry 602 may beplaced, for example, behind the display device 202. The GPS trackingcircuitry may comprise, a GPS chip that is passive or active. The GPScircuitry 602 may then communicate with the display device 202 via thirdlayer 232 when the display device 202 is secured in the housing 210 ofthe securing device. Additionally, the securing device may include anaudio input 604 for connecting it or display device 202 to a headset orother output device. In this way, a user of the connected securing anddisplay devices may track particular fitness related parameters whilelistening to music or the radio.

With regard to the health monitoring functionality of the miscellaneouscircuitry 236, such functionality may allow a user to track certainhealth parameters, including but not limited to heart rate/pulse, skinresistance, skin temperature, blood pressure, and glucose levels. Themiscellaneous circuitry 236 could be integrated into any portion of thethird layer 232, though it is understood that certain health sensorsthat exist currently may be more accurate if placed in direct or closecontact with certain portions of a user's body. For example, turning toFIG. 6(b), placement of a heart rate/pulse sensor 608 on or around theradial artery of the wearer (i.e., on the bottom of the wrist) mayimprove the accuracy of health sensor readings. A battery 610 may beintegrated into the circuitry layer 232 to provide power to the sensoror other components of the securing device or display device 202.Similarly, other portions of the user's body may be more suitable fordirect contact with a health sensor for detecting skin resistance, whichmay help indicate psychological or physiological changes in the user.Such a measurement may allow the wearer to review his health status overthe course of a day to determine which events caused him or her morestress or anxiety. The user may then make appropriate lifestyle changesto reduce that stress or anxiety, if possible. The wearable device 518may include the use of a blood glucose monitor, as illustrated in FIG.6(c). The blood glucose monitor 612 may be coupled to the bottom of thehousing 210. The glucose monitor 612 may also be removable andinterchangeable with other health monitoring components, such as theheart/pulse rate sensor 608 previously discussed.

With regard to the wireless receiving/transmitting functionality of themiscellaneous circuitry 236, such circuitry may include, but is notlimited to, RFID, BlueTooth, NFC, and Wi-Fi circuitry. The circuitrynecessary for these technologies may be embedded into the third layer232 of the securing device. With regard to RFID, Wi-Fi, and BlueTooth,placement of the circuitry may not be as important as the placement ofthe NFC circuitry, as RFID, Wi-Fi, and BlueTooth are capable ofcommunicating at moderate distances. NFC, on the other hand, has a verylimited range and the location of the NFC circuitry on the band mayaffect the comfort level of the wearer when attempting to use thesecuring device for purposes of establishing NFC with another device. Auser may utilize NFC to establish communication with NFC enabled cardreaders to make payments. This may allow a wearer to access a digitalwallet on the wearer's cellular telephone without having to actuallypull the cellular telephone out to establish an NFC connection. Forexample, turning to FIG. 7(a), the miscellaneous circuitry 236 mayinclude an NFC chip 702. This may allow the NFC chip to communicate withother portions of the third layer 232, the display device 202, and/oranother device. RFID may act essentially as a “bar code,” which may beused for numerous purposes, such as security clearance. For instance, awearer of the securing device may gain access to his or her place ofwork by simply wearing a securing device containing the RFID circuitry.This negates the need for the wearer to pull out a clearance or accesscard every time he or she enters their place of work. Alternatively, thecircuitry 236 may comprise BlueTooth circuitry to allow the user tocouple the display device 202 to a cellular phone or other device. Thismay conserve space in the display device 202. While NFC, RFID, andBluetooth have been discussed herein, it would be understood by thosehaving ordinary skill in the art that any wireless circuitry may beutilized within the securing device to allow for data to be transferredbetween wireless devices.

With regard to the illumination functionality of the miscellaneouscircuitry 236, such circuitry may include an LED flashlight capable ofilluminating an area in a dark environment. For example, turning to FIG.7(b), the LED flashlight 704 may be coupled to the third layer 232, butprotrude through the first layer 212 and second layer 224. Theflashlight may utilize a battery 706 embedded into the third layer 232.The battery 706 may be sufficient to provide 120 hours of life to theflashlight 704, while the flashlight 704 may illuminate at 13K-15Kmillicandelas (“MCD”) and require a 4.5V battery.

With regard to the audible, visual, and/or vibratory indicationfunctionality of the miscellaneous circuitry 236, such circuitry mayallow a user to more conveniently determine when a certain event hasbeen triggered by the wearable device 518 and/or a corresponding networkdevice (e.g., a smartphone). For example, a plurality of vibratorymotors may be implemented in the securing device as the miscellaneouscircuitry. When the user receives a cellular telephone call, the usermay be notified by a vibration originating from a single vibratory motorin the third layer 232. When the user receives a text message, the usermay be notified by two vibrations originating from two separatevibratory motors spaced apart on the third layer 232. In yet anotherexample, a user may be notified that a particular person has called byreceiving three vibrations originating from three vibratory motorsspaced apart on the third layer 232; while another person's call may beindicated by two vibrations originating from two vibratory motors spacedapart on the third layer 232. Alternatively, rather than having acertain number of motors vibrate together to indicate a particularcaller or type of notification, the motors may vibrate sequentially tocreate a circular vibration pattern in one direction for one particularcaller or type of notification, and in another direction for a differentparticular caller or type of notification. Likewise, visual indicators,such as light emitting diodes (LEDs), may be utilized in a similarmanner to convey the same information to the user. For example, turningto FIG. 7(c), a plurality of LEDs 708 arranged in a matrix may be builtinto the third layer 232 and protrude through the first layer 212 andsecond layer 224 so that the LEDs may be visible to the user. When analert or notification is received on the user's cellular telephone, theLEDs on the securing device may illuminate to indicate the identity ofthe caller or the contents of the message being received. As would beunderstood by those having ordinary skill in the art, the arrangementand sequencing of the speaker(s), vibratory motor(s), and visualindicator(s) may be arranged or configured in any way suitable to informa user that particular event or notification has occurred.Alternatively, a speaker, vibratory motor, and/or visual indicator maybe implemented in the securing device in lieu of the same circuitry thatwould normally be integrated into the display device 202. This mayconserve space in display device 202. It would be understood that anyfunctionality typically found in a display device 202 may be locatedinstead in the securing device.

With regard to the additional memory functionality of the miscellaneouscircuitry 236, such circuitry may allow a user to store additionalinformation. For example, given the general size constraints of wearabledevices 518 such as smartwatches due to a lack of available space formemory, most smartwatches are significantly limited as to the number ofapplications they may store as compared to smartphones. However, bystoring additional memory in the securing device, a user may storesignificantly more applications. Moreover, a larger number of pictures,video, and/or music could also be stored in the memory of the watch ifthe securing device includes additional memory. Alternatively, all ofthe memory of a display device 202 could be stored in the securingdevice, which would save space in the display device 202.

With regard to the functionality for allowing users to create their ownexternal circuitry on the securing device, the third layer 232 may beconfigured to communicate with a first layer 212 on the outer mostsurface of the securing device which includes a breadboard structurewhich comprises the miscellaneous circuitry 236. For example, turning toFIG. 8(a), an outer circuitry layer 802 in the form of, for example, abreadboard, may be electrically connected to a third layer 232. Theouter circuitry layer 802 may be on the outer surface of the first layer212 and allow a user to add their own circuitry to improve thefunctionality to the securing device. For example, a user may implementtheir own custom LED arrangement and program the securing device ordisplay device 202 to illuminate the LED arrangement as desired.

An additional feature may be a plurality of buttons disposed along thelength of the securing device. For example, turning to FIG. 8(b),buttons 804 may be incorporated into the securing device via the thirdlayer 232. The buttons 804 may be physical buttons that slightlyprotrude from the outer surface of the securing device, or a touchsensor that is completely integrated and embedded into the securingdevice. An embedded touch sensor may be particularly advantageous, as itmay reduce the overall size of the securing device as compared tophysical buttons that may protrude. The buttons or touch sensor may bedisposed on a small portion of the securing device, or wrap around theentire length of the securing device. Buttons or a touch sensor mayallow a user to more easily control the functionality of the securingdevice or display device 202. For instance, a user may stop or play asong on a display device utilizing the buttons 804. As yet anotherexample, a user may answer a telephone call utilizing the buttons 804when the display device or securing device is coupled to a cellulartelephone physically or wirelessly.

With regard to the additional display integrated into the securingdevice, the securing device may include several displays spaced apartalong the length of the securing device, or a single, long, flexibledisplay disposed along a length of the securing device. The circuitry236 of the securing device display 802 may be incorporated as part ofthe third layer 232. The securing device display 802 may allow a user toset the appearance of the securing device based on a theme desired bythe user. Moreover, as will be discussed in greater detail below, thedisplay in the securing device may automatically program itself tovisually correspond to the user interface theme of the display device202. Conversely, the display device 202 may automatically configure itsuser interface to visually correspond to the theme of the securingdevice.

With regard to the functionality of a microphone and/or speaker includedin the third layer 232, this functionality may be advantageous forseveral reasons. First, it may allow a wearer to accept cellular phonecalls on the display device 202 itself by enabling the wearer to use themicrophone and speaker to communicate with a caller. Second, themicrophone may allow the user to utilize voice based commands to operatethe display device 202, the securing device, and/or a correspondingcellular phone wirelessly coupled to the securing device or displaydevice 202.

With regard to the functionality of charging a BlueTooth headset, thefirst and second layers 212 and 224 may be designed to hold or secure atiny BlueTooth headset to the exterior of the securing device. Forexample, a very small latching device or protrusion (not shown) on thestrap may be implemented that is capable of holding a tiny BlueToothheadset. The third layer 232 may be configured to charge a smallultra-capacitor of the BlueTooth headset, the headset only activatingwhen separated from the holding mechanism of the securing device.

Yet another potential feature is the capability to charge the securingdevice or display device via a free end of the securing device. Forexample, either free end of the securing device may comprise a universalserial bus (“USB”) connector, which is electrically coupled to the thirdlayer 232 to allow the user to establish a communication link between anexternal device, such as a laptop, and the securing device or displaydevice 202 secured in the housing 210. Alternatively, the USB connectormay enable the securing device to be charged by another external device,such as a laptop.

The disclosed embodiments may also include circuitry that allows thesecuring device or display device to be inductively charged or passivelycharged using RF. More specifically, inductive charging uses anelectromagnetic field emanated from, for example, a charging pad inorder to charge the display device or securing device without connectingthem to a charger via a physical interface connector. Similarly, passivecharging via RF (e.g., PowerCast RF harvesting) may allow the displaydevice and/or securing device to harvest the energy from radio frequencywaves and provide additional charging capabilities.

An additional feature is the capability of the third layer 232 toautomatically cause an event on the display device 202 when the displaydevice 202 is secured to the housing 210 and electrically coupled to thethird layer 232. For instance, in reference to FIG. 8(c), the userinterface 806 of the display device 202 may automatically be configuredto display a “Louis Vuitton” style theme when a securing device having a“Louis Vuitton” theme 808 is connected. Such a feature would allow auser to own various securing devices, wherein each securing device hasdifferent visual characteristics and automatically causes the userinterface of the display device to match or correspond to the visualcharacteristics of the particular securing device being used. As yetanother example, a user may utilize a securing device corresponding to aparticular sports theme (e.g., Dallas Cowboys), which automaticallycauses the display device 806 user interface to visually correspond tothat particular sports theme. In yet another example, a user may have asecuring device designated as a “sports strap,” which may be moredurable and water resistant. When a user attaches such a securing deviceto the display device 202, certain sports related applications (e.g.,heart rate monitor, distance tracker) and/or themes are loaded by thedisplay device 202, or if such applications are not on the displaydevice 202, those applications may automatically be downloaded by thesecuring device and/or display device 202. While numerous examples ofsuch auto-configuration have been set forth, it should be understoodthat the disclosure is in no way intended to be limited to thoseparticular embodiments. Indeed, the securing device itself could beconfigured to cause any program, setting, or action to occur wheninterfaced with the display device 202, depending on the particularcharacteristics of the securing device. Conversely, the display device202 may cause the securing device to change its configuration. Forexample, when the display device 202 is secured within the housing 210and electrically couples to the third layer 232, the display device 202may cause LEDs on the securing device to illuminate to indicate asuccessful connection. In yet another example, if the third layer 232comprises a securing device display, the securing device display may beset to display a theme corresponding to the theme of the user interface806 of the display device 202 when the display device 202 and securingdevice are first electrically coupled.

Notably, any or all of these features may be implemented into the samesecuring device. For example, many of these features may be implementedutilizing a plurality of miscellaneous circuits 236, each of which isconfigured to add additional functionality as discussed above. Moreover,rather than having a single third layer 232, there may be multiplelayers containing circuitry, each layer having its own miscellaneouscircuitry 236. For example, one third layer 232 may be reservedexclusively for battery circuitry and be disposed along the entirelength of the band, while an additional third layer 232 may be reservedfor a plurality of miscellaneous circuits 236. It would be apparent tothose having ordinary skill in the art that any number of layers ofcircuitry may be utilized, and that additional functionality could beimplemented into the securing device. For example: (1) air bladderscould be integrated into the securing device and inflate to help a usercope with motion sickness; (2) a gyroscope could be integrated into thesecuring device to allow the user to control the securing device or andisplay device using hand or arm gestures; (4) vibratory motors withinthe securing device could vibrate to indicate that a user is not on thecorrect GPS path; (5) health parameters of the wearer of the securingdevice could be detected/monitored and automatically be sent toemergency medical services utilizing the securing device and/or displaydevice; (6) a breathalyzer could be implemented into the securingdevice; and/or (7) a drink tester sensor, which would analyze thecomposition of any drink and display the composition on the displaydevice (see e.g., Vessyl drink analyzer)

Turning now to FIG. 9, a flow chart illustrating the process oftriggering an event based on the coupling of the display device 202 andsecuring device is disclosed. When the display device 202 is firstsecured within the housing 210, the display device 202 and third layer232 attempts to electronically pair at step 902. After pairing issuccessful at step 904, an event is triggered on the display device 202,the securing device, or both at step 906. The event may be, for example,the configuring of the appearance of the theme on the user interface ofthe display device 202 based on the theme of the securing device.Conversely, the event may be configuring of the appearance of a displayon the securing device based on the theme of the display device 202. Atstep 908 it is determined whether additional data is needed to performthe event. If no additional data is needed by either the securing ordisplay device 202 to perform the event, the process continues to step910 where the event is performed. However, if, for example, the eventcannot be performed because of a lack of data, the data is eitherautomatically obtained or the user is prompted to decide whether toobtain the data at step 912. For example, if the event is the changingof the theme of the display device 202 user interface theme, but thetheme is not present in the memory of the display device 202, the thememay be automatically downloaded or the user may be prompted to downloadthe theme at step 912. Once the theme is downloaded, the process movesto step 910 where the event is performed. As yet another example, a usermay begin pairing a fitness securing device and display device 202 atstep 902. If pairing is successful at step 904, the securing device mayattempt to trigger an event on the display device 202 at step 906 byautomatically running certain fitness related apps. If the apps arealready on the display device 202 at step 908, the fitness related appswould automatically run at step 910. However, if the fitness apps arenot on the display device 202 at step 908, the fitness apps would eitherautomatically download or the user would be prompted to download theapps at step 912. While only two examples are given here, it would beapparent to those having ordinary skill in the art that the securingdevice and/or display device 202 could be configured to trigger anyevent on the securing device and/or display device 202. Moreover, theuser could program the trigger settings using an interface on either thedisplay device 202 or the securing device itself. Additionally, the usermay cause any event to occur upon the pairing of a particularcombination of securing device and display device. Also, the disclosedprocess may apply (as previously discussed) when a particular module 502or modules of the securing device are connected to the display device orto another module. For example, the connection of a module 502 relatingto GPS tracking may trigger an event or action to occur on the displaydevice. Conversely, the connection of the GPS module 502 may cause anevent or action to occur on the GPS module 502 itself. Similarly, theconnection of multiple modules 502 as part of the securing device maycause an action to occur that would otherwise not occur when themultiple modules 502 are connected individually. For example, theconnection of a module 502 relating to GPS tracking and health statusmonitoring may cause a jogging application to be downloaded andactivated on the display device, whereas the connection of the GPSmodule 502 for health status monitoring alone would not cause that eventor action to occur.

While the figures show the securing device as a band in many instancesit would be understood by those having ordinary skill in the art thatother types of securing devices may be used. For example, a bike helmetmay include integrated circuitry and be used as a securing device toreceive a display device. As yet another example, a brooch or pin mayinclude integrated circuitry and be a securing device to receive adisplay device. As yet another example, a necklace or earring mayinclude integrated circuitry and be a securing device to receive adisplay device.

FIGS. 10A-10C illustrate an alternate embodiment of a securing device,shown as a band 1000 attached to a display device, in this case a watch1002. The band 1000 has an overlay portion 1004 which overlays the back1006 of the watch 1002. The overlay portion 1004 is such that theoverlay portion 1004 covers contacts 1008 on the back 1006 of the watch1002. As the overlay portion 1004 is located behind the back 1006, asthe watch 1002 is worn on a wrist, the overlay portion 1004 will bepressed into the back 1006 of the watch 1002 so that the contacts 1008will be fully covered. If the clasp portion 1010 of the band 1000, whichcontains the overlay portion 1004, is rotated, the contacts 1008 may beexposed. FIG. 12 provides a back view of the watch 1002, showing thecontacts 1008.

FIG. 11 illustrates a version of the clasp portion 1010, referred to as1010′, with an overlay portion 1004′. A series of wires 1014 areprovided externally, rather than internally as shown in FIG. 10C, andthe overlay portion 1004′ is separated from the clasp portion 1010′,being retained by a spring biased pin 1016, rather than being integralwith the clasp portion, with the spring biased pin 1016 being locatedabove the internal wires. The illustrated spring biased pin 1016 is aquick release pin and is described in more detail below. A series ofpogo pins 1012 are located in the overlay portion 1004′ and are locatedto align with the contacts 1008. As shown, two of the pogo pins 1012 andcontacts 1008 are ground, one pogo pin 1012 and one contact 1008 ispower, such as 5V and the final pogo pin 1012 and contact 1008 is singlewire serial interface. The pogo pins 1012 are connected to the wires1014 to allow access to the components, as discussed above, in the band1000. Thus, when the watch 1002 is being worn, the pogo pins 1012 are incontact with the contacts 1008 and the function in the band 1000 isoperational.

FIGS. 14A and 14B are views of power cables 1400 for use with a displaydevice 202, like that shown in of FIGS. 10A-10C as 1002. A first end1402 is configured to be plugged into a USB port to obtain power andground to allow charging of the display device 1002. A second end 1404has a series of pins 1406 connected to the power and ground providedfrom the USB end 1402, the pins being arranged to mate with the contacts1008 on the back 1006 of the display device 1002.

By having both the overlay portion 1004 and the second end 1404 havingpins 1012, 1406 arranged to match the single set of contacts 1008, onlya single set of contacts 1008 is needed to both charge the displaydevice 1002 and communicate with the circuitry in the securing device1000. When the display device 1002 is being worn, as stated above, theoverlay portion 1004 is in connected to the contacts 1008. When thedisplay device 1002 is not being worn and the clasp portion 1010 isrotated as mentioned above, clearance is provided to allow the powercable 1400 to be used to charge the display device 1002. This provides avery simple way to both provide additional functions as described aboveand to charge the device.

FIGS. 13A-13C illustrate more details of the spring biased pin 1016. Thespring biased pin 1016 is different from a normal spring pin used toattach a watch band to a watch as it includes a projection 1302 for useto retract a protruding pin 1304. The projection 1302 is simply slidtoward the center of the spring biased pin 1016 in a slot 1306. Thisretracts the protruding pin 1304, allowing the securing device to bevery simply removed from the display device. A spring (not shown)contained inside the spring biased pin 1016 in a normal manner keeps theprotruding pin 1304 in contact with a recess in the display device sothat the securing device is attached. In the embodiment of FIGS. 13B and13C, the protrusion 1302 is provided to the top of the band through anopening 1308. In the embodiment of FIGS. 10B and 10C the protrusion 1302is provided on the bottom side of the band. The protrusion 1302 may bemade flush with the surface of the securing device.

The spring biased pin 1016 may be used with the various embodimentswhere the securing device contains circuitry as described above, as theprotrusion 1302 allows very simple operation to remove the securingdevice. A normal spring pin is difficult to remove, often requiringspecialized tools, making changing a band challenging. By being easilyremovable the securing device can readily be changed should the userdesire, which would permit securing devices capable of supportingdifferent functions, such as using a battery for extended life, oradding a GPS sensor for more accurate user tracking.

It will also be understood that the above description is intended to beillustrative, and not restrictive.
